"A group of soldiers of the caliphate in Indonesia targeted a gathering from the crusader alliance that fights the Islamic State in Jakarta through planting several explosive devices that went off as four of the soldiers attacked with light weapons and explosive belts," the group said in a statement.

A news agency affiliated to Islamic State also reported the group was behind the attack.

Jakarta Police Chief Tito Karnavian revealed the attackers were linked to IS in Raqqa, Syria, in particular an Indonesian named Bahrun Naim.

"He wants to be the leader of ISIS groups in Southeast Asia," he said.

Following the Paris terror attacks, the International Crisis Group's Sidney Jones warned against complacency, highlighting a blog post by the ex-prisoner where he praised the Paris attacks and called on readers to take notes.

Before Christmas, and acting on intelligence from Australia and the US, Indonesian authorities disrupted a network planning ISIS-inspired attacks on police and New Year celebrations.

In their communications they were referring to "a concert", believed to be a reference to Paris.

Meanwhile, reports of fresh explosions in the capital on Thursday night were only a blown truck tyre, revealing the city was still on edge after the day's events.
